PLOS One, 2026The treatment gap, measured
A 2018 household survey of 1,892 adults aged 40 and over in Bo district applied the WHO and International Society of Hypertension risk calculator, then checked who was actually receiving the treatment they needed.

What this means for Sierra Leone
- The need is large and almost entirely unmet. Nearly half of adults over 40 in Bo met the criteria for hypertension treatment. Around one in eight of them was receiving it. Not one person who needed a statin was on one.
- This is a funding decision, not a capability problem. The same facilities score 41% ready for HIV care and 17% for cardiovascular care. HIV services in Sierra Leone received roughly 30 million dollars in 2017. All non-communicable disease care received 510,000 dollars. What sustained investment can build is visible in the same buildings.
- Guidelines cost almost nothing and are entirely absent. No facility in Bo district held guidelines for diagnosing or managing cardiovascular risk. That is the cheapest gap on either chart to close.
- The economic argument is about working-age adults. These conditions strike people who are earning and supporting households. Care arrives late, is paid for out of pocket, and the household absorbs both the treatment cost and the lost income. Prevention at primary care level is far cheaper than the stroke ward.
